This strategy is based on the value of two SMA. One based on close and other on open. It is NOT based on crossover but based on using one SMA at one time. For example, the value of GOLD and two SMA's, i.e., SMA(close,length1) for buying and SMA(open,length2) for selling. Feel free to use. Its open for all, but the source code is hidden, so that i could make further changes and improvements without any problems.
